Frequently Asked Questions
Both materials are used for insulation, bundling, and protection, but they suit different needs. PVC heat shrink tubing shrinks at a lower temperature, offers enhanced flame retardancy, and its clear versions stay transparent over time, which makes it a cost-effective choice for heat-sensitive components and PVC jacketed wire. Polyolefin heat shrink tubing is available in higher shrink ratios, such as 3:1 and 4:1, and is often chosen when the tubing needs to recover over larger or more irregular shapes.
PVC heat shrink tubing has an operating temperature range of -4°F to 221°F (-20°C to 105°C). It also has a low shrink temperature, so it can be installed with less heat than many other shrink materials, which helps protect heat-sensitive components nearby. For applications above 221°F (105°C), polyolefin or fluoropolymer heat shrink tubing may be a better option.
Our PVC heat shrink tubing has a 2:1 shrink ratio and is available in sizes from 3/64" to 4". Choose from standard wall (.020") or heavy wall (.031") options. Standard colors include black, white, red, yellow, blue, and clear, with black as the standard color for heavy wall tubing.
Yes. All of our PVC heat shrink tubing colors, including clear, are UL-VW-1 flame retardant. The tubing meets UL, CSA, and military specifications, complies with ASTM D 3150, and is RoHS compliant and lead-free. If your program calls out a specific military specification, contact our team to confirm the right part number and documentation.
No. Our clear PVC heat shrink tubing is designed to stay crystal clear without yellowing, clouding, or cracking. It also resists UV light, chemicals, oils, and moisture, so it works well in indoor and outdoor applications where labels, color codes, or the underlying component need to stay visible.
Yes. Adhesive-lined PVC heat shrink tubing is available for applications that need a tighter seal. When heat is applied, the inner adhesive lining melts and flows to fill gaps around the wire or component, adding protection against moisture and contaminants. Our team can help you decide whether adhesive-lined tubing is the right choice for your application.
Yes. PVC heat shrink tubing is commonly used for wire and cable identification and color coding. Colored tubing makes it easy to separate circuits at a glance, while clear tubing can be placed over labels to protect them without blocking visibility.
